多属性储层参数反演方法在M油田中的应用
|
摘要
针对油田开发阶段对储层表征的精细程度需求,通过充分利用已钻井获取的储层参数信息,优选对储层反演目标参数具有较好反映的多个地震属性,通过线性和非线性方法建立地震属性与反演参数之间的对应函数关系,同时对井震标定、外部属性输入和井震资料匹配三个关键环节进行优化和质控,实现了高分辨率的储层反演。该技术在M油田的应用效果表明,反演结果的纵向和横向分辨能力明显提高,反演结果可以精确刻画储层厚度及内部结构特征,与钻井结果有较高的吻合度。
In order to satisfy the fine reservoir characterization at the development phase of the oilfield, we took a full use of reservoir information obtained by drilled wells to select several seismic attributes, and established the relation of the linear and nonlinear mapping between selected seismic attributes and inversion reservoir parameters to achieve the high-resolution spatial prediction of reservoir parameters. The application of seismic multi-attributes inversion in M oilfield showed that the vertical and lateral resolution of inversion result was significantly improved, and the predicted results agreed well with the drilling results.
